Original application February 8, 1936, Serial No. 68,037. Divided and this application June 2,

1936, Serial No. 83,051

6 Claims.

This invention relates to methods of producing encircling bands, and in particular a band having an adhesive coating at each end on' opposite sides thereof and which coatings are placed together and caused to adhere by pressure, to unite the ends of the band together. Such a band is disclosed and claimed in my co-pending application Serial No. 63,037, filed February 8, 1936 and of which, this application is a division made 10 in compliance with ofiicial requirements.

Encircling bands as presently employed are usually coated at one end thereof with paste, glue, mucilage or other adhesive which is wet or wetted at the time the band is being placed around the article and unless great care is exercised in placing the band end coated with wet adhesive in superposed contact with the opposite band end, the adhesive is smeared onto the article with resultant soiling of the article or the band becoming attached to the article.

Also a wet adhesive is objectionable in the operation of automatic machines for applying encircling bands, as such an adhesive interferes with the normal functioning of the automatic feeding, conveying and applying devices of such a machine.

I propose to avoid these difliculties by providing an encircling band having a coating of adhesive at each end and on opposite sides thereof and which coatings will adhere only to each other and will cause the band to be united together,

when pressure is applied to the overlapped ends thereof, at the time the band is placed around the article.

I also propose to employ a method of applying such an adhesive at the opposite ends of the band on opposite sides thereof so that difficulties normally to be encountered in the manufacture of such'a band will be obviated.

It is the primary object of my invention to provide a novel and improved method of producing an encircling band having a coating of adhesive at each end on opposite sides thereof and which adhesive by adherence under pressure will unite together the ends of the band.

It is another object of my invention to provide a method of producing an encircling band having such a coating of adhesive applied on opposite sides at the ends thereof with an un- 60 coated protective area between the edges of the coatings of adhesive and the band edges.

It is another object of my invention to provide a method of applying such an adhesive in a novel manner at the opposite ends of the band 55 on opposite sides thereof for obviating the above referred to difificulties normally to be encountered in the manufacture of such a band.

It is another object of my invention; to provide a method of applying such a coating of adhesive that the location thereof is controlled 5 to avoid the above mentioned difiiculties to be encountered under known practices.

It is a further object of my invention to provide a method by which such coatings of adhesive may be applied to a plurality of bands 10 that are disposed together in pre-determined attached relationship and individual bands produced therefrom through the use of well-known. devices and at the same time avoid difliculties 15 therein.

The accompanying drawing illustrates the manner of producing, and bands resulting from the practice of my method; it being understood however that no limitation is necessarily made to the precise details therein shown, but that alterations and modifications within the scope of the appended claims may be resorted to when desired.

The parent application of which this is a di- 25 vision, will retain a description and illustration of my improvements in encircling bands and for this reason it is deemed advisable to retain in the present application the designations of parts used in the original application in order 30 that the two may be read together or that crossreference may be conveniently made from one to the other.

Also While the word band has been used for purposes of brevity, it is to be understood that 35 this term shall broadly include labels or other forms of encircling or wrapping devices which are analogous to bands.

In the drawing:

Fig. 1 illustrates a fragment of a large sheet 0 on which is depicted a plurality of shaped bands, and showing the coating of adhesive on the obverse side of the band. In this view the shaped bands are shown as a plurality of bands in a plurality of rows with indications of the manner in which the individual bands are separated from each other by a die plate;

' Fig. 2 illustrates a fragment of a large sheet on which is depicted a plurality of oblong bands and the manner of separating them from each other and from the sheet. The coating of adhesive is also shown on'the obverse side of the bands in this view;

Fig. 3 illustrates an individual band or fiat strip died from a sheet such as illustrated in Fig. 1 and 5;,

shows the coating of adhesive on both the obverse and reverse sides thereof;

Fig. 4 shows the flat strip or band illustrated in. Fig. 3 after the ends have been united together by pressure to cause adherence between the coatings of adhesive;

Fig. 5 illustrates an oblong band or flat strip separated by cutting from a sheet such as shown in Fig. 2 and shows the coating of adhesive on both the obverse and reverse sides of the band;

and I -Fig. 6 shows the oblong fiat strip band illustrated in Fig. 5 with its ends partially united through pressure upon the coating of adhesive after one end has been lapped over the other.

Referring to the drawing in detail wherein similar reference characters designate corresponding parts throughout the several views; In is a fragment of a large sheet of paper, fabric or other suitable material, having delineated thereon a plurality of shaped bands II. The shape of bands II is that commonly used for encircling cigars, confections and other cylindrical articles. If printed, bands I I are arranged on a large sheet I8 and a plurality thereof are printed in a plurality of parallel rows I2. After the printing operations are completed the parallel rows I2 of bands I I are separated from each other along the lines indicated as I3 in Fig. 1 for the subsequent operation of dieing out individual bands I I to the form shown in Fig. 3.

Before separating the parallel rows I2 of bands I I from each other, I prefer to apply areas of adhesive coatings I4 and I5 on the obverse and reverse sides respectively of sheet I8 to coincide with the respective ends I6 and II of bands II. The areas of adhesive coatings I4 and I5 may be applied to the sheet I0 through the use of wellknown printing presses or other instrumentalities which provide for applying inks, gums or varnishes in controlled or registered positions on a sheet.

It will be noted that I have illustrated the areas of adhesive coatings I4 and I5 to be less than the areas of band ends I6 and H to provide uncoated surface areas I8 and I9 at the band ends I6 and II lying between the coated areas I4 and I5 and the edges of the bands I I. The purpose of the uncoated areas I8 and I9 will now be described: After the sheet III has been coated with adhesive areas I4 and I5 as before set forth, it is then cut into parallel rows I2 of a plurality of bands II as indicated by lines I3. When cutting sheet. I8 into parallel rows I2 it is customary to operate upon a pile or lift of approximately 500 sheets. Should thebands be embossed, then the "lift of sheets handled is greatly lessened in number due to swell in the embossing. After the sheets I0 have been cut apart along lines I3, the separate "lifts or piles are then fed through a machine employing a die plate which cuts through the lift and removes a lift of individual bands or flat strips II at each operation. By providing the uncoated areas I8 and I9 around the areas of adhesive coatings I4 and I5 and controlling these areas I8 and I9 in register with the ends I6 and I1 of bands II, I provide an operating space for passage of a cutting machine knife when cutting the pile or "lift of sheets II) at lines I3 and the die plates when separating the individual bands or flat strips I I. It is thus clear that the coatings of adhesive I4 and I 5 will not be engaged by either of these instrumentalities. I have found that in applying coatings of adhesive without my uncoated protective areas I 8 and I9 therearound,

to sheets that are to be subsequently cut up into small flat strips or parts, that the adhesive tends to follow the cutting or dieing instrumentality and drag and smear along the edges of the work being cut, thus uniting the adhesive and hence all of the bands or flat strips together at the edges and bands in such condition are exceedingly difficult if not impossible of handling in automatic band applying machines.

In the form of band shown in Fig. 2 the operation of applying the areas of adhesive coatings I4 and I5 are carried out in the identical manner before described including providing the uncoated protective areas I8 and I9 around the coated areas I4 and I5 at the band ends I6 and II. All of the operations necessary to produce a band or fiat strip II such as shown in Figs. 1, 3 and 4 are also necessary to produce a band or flat strip 2I such as shown in Figs. 2, 5 and 6, with the exception that, as band 2| is oblong in form, the usual cutting operation alone is employed. Fragment of sheet 28 of Fig. 2 comprises a plurality of bands 2I in a plurality of rows 22 similar to those described for sheet III of Fig. 1. After the areas of adhesive coatings I4 and I5 have been applied. to sheet 20 by printing, gumming or spotting on well-known instrumentalities, in registered location, sheet 28 is cut up into a plurality of single bands or flat strips 2| as indicated at 23 and 24. The adhesive that I prefer to employ in connection with my improved band and the methods of producing same, is one in which when in a dry state adherence or coherence will occur only between coatings of the same substance. Such an adhesive, and one which I find suitable for my purpose, is prepared by dissolving India or Para rubber in gasoline or benzine to proper consistency for application by printing presses, gumming machines or other instrumentalities to my improved band. I have also found that latex may also be adapted to my purpose. The solution is printed, spotted or gummed onto the sheets in the well-known manner and upon evaporation of 'the solvent the residue becomes a dry adhesive that will not adhere or cohere to other than coatings of the same substance.

While I have described myimproved band as being a band printed upon or produced from a large sheet, it is obvious that any printing operations relating to the band may be eliminated and only the operations of applying controlled areas of adhesive coating in controlled places upon the sheet, employed. Also it will be obvious that I can produce my improved band in single rows by printing on or producing from small sheets.

It will appear from the foregoing that I have provided a method of producing an improved and novel form of encircling band having a coating of adhesive at each end on opposite sides thereof and which adhesive under pressure will unite together the ends of the band.

It will also appear that I have provided a method of producing an encircling band having such a coating of adhesive applied on opposite sides at the ends thereof with an uncoated protective area between the edges of the coatings of adhesive and the band edges.

It will alsoappear that I have provided a method of applying an adhesive coating so that the location thereof is controlled to avoid difficulties normally encountered in band.v manufacture.

It will also appear that I have provided a method by which an adhesive coating of the character described may be applied to a plurality of bands through the use of well-known devices I is:--

1. The method of producing flat strips to be used as encircling bands, which method consists in applying adhesive coatings to the obverse and reverse sides of a sheet within controlled areas disposed in definitely spaced relation to the marginal edges of the strips, then in cutting the sheet along a line extending between and spaced from the marginal edges of said controlled areas.

2. The method of producing fiat strips to be used as encircling bands, which method consists in applying adhesive coatings to limited areas of the obverse and reverse sides of a sheet, said adhesive coatings being disposed in definitely spaced relationship to the marginal outline of the finished strips, then in cutting the sheet along said marginal outlines to sever the strips from the sheet.

3. The method of producing fiat strips to be used as encircling bands, which method consists in applying adhesive coatings to selected restricted areas of the obverse and reverse sides of a sheet, the coated areas being arranged in definitely spaced relationship to the marginal outlines of the finished strips, and in severing the strips along said marginal outlines to separate them from the sheet. v

4. The method of producing flat strips to be used as encircling bands, which method consists in applying adhesive coatings to limited areas in predetermined relative arrangement on the obverse and reverse sides of a sheet, and in cutting the sheet in predetermined marginal outlines of the finished strips enclosing the adhesive coatings of the respective strips, the marginal edges of said adhesive coatings being spaced from the marginal outlines of the strips upon which they respectively occur.

5. The method of producing printed flat strips to be used as encircling bands, which method consists in printing upon spaced areas of a sheet within the marginal outlines of portions subsequently cut therefrom to constitute the strips, in applying to limited areas of opposite sides of the strip constituting portions, coordinated patches of adhesive coatings, and in cutting said sheet along the marginal outlines of said portions to sever the strips from the sheet.

6. The method of producing printed fiat strips to'be used as encircling bands, which method consists in printing upon spaced areas of a sheet lying within the marginal outlines of portions respectively which are to constitute the strips, in applying to opposite sides. of said portions patches of adhesive coatings terminating marginally within and spaced from said marginal outlines to provide uncoated protective areas, and finally in separating the strips from the sheet by die cutting operations coincident with said marginal outlines.
